WHEEL MOUNTING.

yApplication filed October 7, 1924. Serial No. 742,157.

This invention relates to the construction of a vehicle wheel mounting and means for lubricating the pivotal partsV included with the mounting.

As illustrated in the drawlngs attached hereto, my invention is particularly adapted for use in connection with the front wheels of an automotive vehicle, in connection with which brakes are used. From many stand; points, internal brakes are preferable for the front wheels of an automobile, butl the mounting Iof brakes on front wheels 1s far from a simple problem. I

llt is therefore, one of the objects of my invention to provide a wheel mountlng comprising a spindle for the wheel and a plate integral with the spindle, which plate can be utilized for mounting the brakes; also the same plate carries integral parts whlch support the end of the axle through the medium of suitable bearings and a plvot or what is commonly termed a king pin.

Another object of my invention is. to provide means for securely holding the king pin in position in the end of the axle, which means also serves the double function of passing lubricant to the king pin, whlch is made hollow preferably `from end to end.

Another object of my invention 1s to provide means associated with the king pin andits bearings for preventing the lubricant from escaping, thereby more nearly insuring proper lubrication of these parts.

These and other objects will be clear from the following description taken in connection with the annexed drawings wherein:

Figure 1 is a sectional view of the Wheel support associated with the end of the axle.

Figure 2 isa section on a much reduced scale of the wheel spindle and integral plate, taken on the line 2 2 of Fig. 3. i

Figure 3 is a right hand end view of Fi 2.

igure 4 is a section on the line 4-4 of Fig. 3; while igure 5 is a fragmentary left hand end view of Fig. 1, showing the brake anchorage and part of the brake operatmg means.

Referring now to the detalls, whereln like numbers refer to corresponding parts 1n the various views, 1 is a wheel spindle having an integral plate 2 with bosses 3 and 4 there` on. The plate also carries a boss to which is attached a steering arm. The s indle 1 carries a wheel generally referre to as 5, one of the bearings 6 bemg shown.

The plate 2 extends away from the spindle 1 preferably in an upward direction as indicated for the purpose of supporting the brakes, which are preferably of the self-energizing type in which the brake anchorage 7, for what is generally termed the secondary shoe, passes through the orifice 8; while the brake operating mechanism or its bearing 'is positioned in orifice 9 in the plane of bosses 3 and 4. The brake operating mechanism preferably consists of an operating shaft 12 connected through a universal joint 13 witlra control shaft 14, the inner end of whch is usually supported on the side of the cli-amis in any satisfactory manner. The operating member 12 is carried in a member 15 which tits. the hole 9, being clamped to the plate 2 by a nut 16. On the end of the operating shaft 12 is a member 17 which connects with lthe free end of one of the brake shoes.

The end of the axle 18 is positioned between the bosses 3 and 4 in which are positioned similarly shaped bearing bushings 19 and 20. The end of the axle 18 preferably has a tapered hole to receive the king pin 21. which has a tapered portion substantially equivalent to the thickness of the axle. The upper end of the pin 21 is tapered also and the lower end. may .be straight to form bearingsurfaces in the bushings 19 and 20. Each of the bushings is provided with a Hange 22 on the end toward the axle. Between these flanges and the axle are disposed suitable bearing members 23, one or more of these being used atthe bottom part of the axle, all being enclosed within a collar 24, which preferably fits snugly over the flange 22 of the bushing 20. It. is to be noted that the in 21 has a hollow portion 25 extending rom end to end, while each of the bashings 19 and 20 are provided with an annular groove 26 and a passageway 27 leading from the annular groove to the hollow part of the pin, whereby lubricant is carried to the bearing surfaces between the ends of the king pin and thebushings 19 and 20. Of course the grooves may be made in the pin itself and accomplish a similar result.

A lubricator 28 of any desired type is screw threaded into the end of the axle and is locked in placed by a nut 29, while the end 30 of the lubricator extends into the tapered portion of the pin 21 in such a manner asto tend to continuously force the pin -and the scope of the appendd claims.

21 on to its tapered seat. This lubricator may be of a type in which force lubrication is used whereby lubricant can be forced into the grooves 26 and 27 aswell as elsewhere. This construction also helps to keep the pin 21 from turning vin its seat. A passageway 31 is provided, leading from the hollow part of the pin to the lubricant passageway of the lubricator. In order to keep dust and dirt out cf the kin pin bearingsand to hold the lubricant within the parts ,described, the ends of the bushin'gsll) and 20 are extended and .preferably threaded to receive caps 32 and 33, packing washers 34. being utilized to seal the joints tightly between the caps and the bosses.

It will thus be seen that I have provided vvery effective means for mounting and'.

lubricating the wheel spindle as well as providing a very rigid support for the brake mechanism, as it is to be understood that the preferable way of making the integral spindle and plate is from a drop forging. As will be clearly seen from Fig. 1, the spindle side of the plate is preferably smooth to receive a cover plate 35 :for the drum, the same being fastened to plate 2 through the medium of the screw holes 36 shown in dotted lines, Fig. 3.

It will be further understood that various changes may be made in the detail construction entering inte my invention without departing from the lspirit of the same Having Vthus described my invention, what I claim is:

1. The combination with an integral wheel spindle and plate having bosses thereon, an axle positioned between said bosses, a pivot pin supported in said axle and passing through said bosses and a combined holding pin and lubricator positioned in the axle and extending into said pivot pin.

2. In combination with an integral wheel spindle and plate having bosses thereon. an axle positioned between said bosses, a hollow pivot pin vcarried in the end of said axle and projecting through said bosses, bushings in said bosses on said pin ends, each of said bushings having at least one annular lubricant retaining groove inter- Patent No. 1,613, 768.

neiavee mediatezitsends with a passage in the pin leading from the groove to the hollow of the pin, a lubricator Jrpositioned in the end of the axle and -pushing' downward on the pin and a passage leadlng from the lubricator to the hollow part of the pin, and closure caps securely attached to the ends of said bushin s for the purpose described.

3. In com ination with an integral Wheel spindle Vand plate having bosses thereon, an

axle positioned between said bosses, a hol said pin, and closure ca s securely attached.

to the ends of said bushlngs for the purpose described. 'n

4. In combination with an integral wheel spindle and late having bosses thereon, an axle positioned between said bosses, a hollow pivot pin having a tapered portion in the end of said axle and straight portions extending into said bosses, bearing bushings in the bosses for said straight pin portions, unitary means for holding said pin on its tapered seat and for passing lubricant to the center of the hollow of the pin, and means on the ends of said bushings for retaining the lubricant.

5. In combination with an integral wheel spindle and plate having bosses thereoi-a. ositloned between said bosses, a'

an axle hollow pivot pin having altapered portion in the end of said axle and having pivot ends extending throu h said bosses, bearing members interpose between said flanged ends and the axle end, unitary means forl holding said pin on its tapered seat and for passin lubricant tothe center of the hollow o the pin. w

In testimony whereof, I alix my signature.
